Structure and formation of DNA. This double helix molecule
stores genetic information through sequences of nucleotides and
nitrogenous bases. Its enzymatic replication process allows the
precise transfer of the biological code during cell division for
inheritance purposes.
Human skin consists of the epidermis, dermis, and hypodermis.
along with follicles, glands, and vessels that protect the body,
regulate temperature, and enable sensory perception.
The structure of alveoli shows microscopic air sacs located at the ends of bronchioles. These small lung structures are responsible for oxygen and carbon dioxide exchange during respiration.
The structure of the mammary lobes explains how glandular tissues are organized inside the breast. Each breast contains lobes, lobules, and ducts responsible for milk production and transport during breastfeeding.
The structure of the neuron is composed of three
main parts: the soma, the dendrites, and the axon.
The soma or cell body contains the nucleus and
regulates the essential functions of the cell.
The small intestine structure includes the duodenum, jejunum, and ileum. Its mucosa has villi and microvilli that increase the absorption surface and allow efficient nutrient uptake in the digestive system.
Subcapital femoral prosthesis is a surgical treatment for
severe fractures near the femoral head. Moreover, it replaces
damaged structures, relieving pain and restoring mobility.
Indication depends on patient age, health, and fracture severity.
Suspensory ligaments of the breast, also known as Cooper’s ligaments are fibrous connective structures that support breast tissue and help maintain the natural shape and stability of the breasts.
Synapse, beta-amyloid protein, and neurofibrillary tangles
in Alzheimer’s disease. The neuronal synapse is
the point of communication between neurons and plays
an essential role in the functioning of the nervous system.
The synapse in Alzheimer’s disease has an altered function in
neuronal communication. Moreover, under normal conditions,
synapses allow efficient signal transmission. Additionally, they
support memory and learning.
Parkinson’s disease. It is characterized by the loss of dopamine-producing
cells in the brain. This dopamine deficiency leads to motor and non-motor
symptoms, such as balance problems and cognitive alterations.
